The 850-year-old Notre-Dame cathedral in Paris, one of the world’s most iconic buildings, was devastated by a fire on April 15, 2019 during renovations, which destroyed much of its roof and spires as well as the cathedral’s nineteenth-century clock. Unfortunately, there were no plans or digital files of the clock. Luckily, though, a nearly identical clock movement was recently discovered and a passionate team is working to use that as a template for (funds permitting) rebuilding a new clock for Notre-Dame.
